Dampening piston for hydraulic telescopic vibration damper

摘要

The dampening piston comprises of a piston body (1) provided with valve discs on both end faces, and firmly connected with a piston rod. The piston body has a group of openings (4,7) for the pull and thrust directions. Each opening in the piston body is blind-hole like and is built parallel to a piston axle's (3) continuous recesses (5,8). Each continuous opening (6,9) about the piston axle may be built through a continuous circular-arc shaped depression parallel to the end faces of piston body. Each recess, on the outlet side end, may have a larger cross section than the region of recess base (5'8').
